4 Claims.

The present invention pertains to window construction and more particularly to sliding sash of the pick-up type wherein the main sash member slides in a window-opening direction independently for a predetermined distance and thereupon picks up the supplemental sash member, after which both move in unison to thefully open position; and in the window-closing direction both move together to the closed position of the supplemental sash member and thereafter the main sash member moves independently to its closed position.

The primary purpose of the invention is the provision of a particularly efiicient simplified assembly permitting the accommodation of the sash members in a recess offset from the line of sash travel and out of parallelism with the plane of the window opening.

The invention is particularly adapted to the vertically sliding main and transom sash members of railway cars and motor coaches although applicable to other situations including sash members arranged in multiple to slide in a general horizontal rather than a vertical direction.

Other situations to which the invention may be adapted will be apparent to those skilled in the art and within the scope of the invention as defined in the appended claims.

Inorder that the features of the invention may be readily understood one exemplification of the same is hereinafter described in connection with the accompanying drawing, wherein Fig. 1 is a detail inside view of the window opening and sash members in closed position;

Fig. 2 is an enlarged vertical section through the sash members and frame with the former in closed position;

Fig. 3 is a similar view with the sash members in open position; and

Fig. 4 is a further enlarged cross section through sash and frame at right angles to Figs. 2 and 3.

Having particular reference to the structure illustrated in the drawing, the coach, car or the like is indicated at H provided with the window opening bounded at the sides l2 and bottom |3 by the window frame l4 and open above to a recess I5 between the inner and outer walls l6 and I! which, as here shown, extend upwardly to form the domed deck or roof in an arcuate direction out of parallel with the plane of the window opening. I 1

The window frame I4 is provided on each vertical side with stops forming therebetween guide grooves l8 for the lower main sash I9 and for the supplemental transom sash 2|. The lower rail 22 of the main sash I9 is provided with a cushioning member 23 for contacting the sill l3 and its upper rail 24 may be provided with a suitable weather stripping 25 to effect a close fit when in closed position with the lower rail 26 of the sash 2|. The guiding relation between the guide grooves l8 and 20 and the respective sash members I9 and 2| may be efiected in known manner but the guide members 21 are here shown as of the floating type, having a resilient relationship to the sash proper. Stops 28 affixed to the side walls of the window frame limit the downward movement of the upper sash member 2| so that when in closed position the meeting rails 24 and 26 of the two sash members will lie side by side as shown in Fig. 2.

The upper rail 24 of the main sash I9 has aflixed thereto a plate or bracket 29 which is adapted to engage with a bracket 30 of general- Z-shape attached to the upper rail 3| of the secondary sash 2| and extending upwardly and laterally into the path of the bracket 29 when and not until the sash H! has been lifted to a position where the lower rails of each coincide horizontal- 1y; after which the two sash members actuated by the lifts 32 move in unison upwardly into the recess l5, as represented in Fig. 3.

It will be observed that the upper rails 24 and 3| of the two sash members are caused to assume a staggered relationship due to the fact that the bracket 30 is formed as an extension from the upper rail 3| of the supplemental sash and is not engaged by the plate 29 of the main sash until the upper rail of the one has passed the upper rail of the other. This staggered arrangement adapts the upper portions of the sash members for accommodation within the offset recess l5 and thus enables the sash members to be withdrawn more fully from the window opening than would be possible without such offset relationship.

I claim:

1. In a pick-up window sash assembly, the combination with a window frame bounding a window space upon three sides and opening at the fourth side into a recess, the frame presenting opposed parallel spaced guides in alignment with the entrance to the recess, of a plurality of sash members slidable along the guides in parallel planes, an upper one of the sash members carrying a bracket projecting upwardly beyond its upper edge and then laterally into the path of the other sash member for engagement thereby after the upper edge of the other sash member.

passes beyond the upper edge of the first sash member, whereby as one of the sash members is opened it moves independently of the other member until it engages the bracket and thereafter the two move in unison into the recess with the upper edges in staggered relation;

2. In a pick-up window sash assembly, the combination with a window frame bounding a window space below and at the two sides and opening above into a recess, the frame presenting parallel spaced guides in alignment with the entrance to the recess, of upper and lower sash members slidable along the guides in parallel planes, an upper member carrying a bracket extending upwardly beyond its upper edge into the recess and then projecting laterally into the path of the next lower member for engagement thereby, whereby as a lower sash. is opened it moves upwardly independently of the upper member until it engages the bracket and thereafter the two move in unison into the recess with. the upper edges in staggered relation.

3. In a pick-up window sash assembly, the combination with a window frame bounding a window space below and at the two sides and opening above into a recess offset out of parallelism with the plane of the window opening, the frame presenting opposed parallel spaced guiding grooves, in alignmentwith the entrance to the recess, of upper and lower sash members slidablev along the grooves in parallel planes, the upper sash member carrying a Z-shaped bracket 'window space below and at the two sides and I opening above into a recess offset out of parallelism with the plane of the Window opening, the frame presenting opposed parallel spaced guiding grooves in alignment with the entrance to the recess, of upper and lower sash members slidable along the grooves in parallel planes, a stop limiting the downward movement of the upper sash to that portion of the window open ing adjacent therecess, the upper sash member carrying a Z-shaped bracket extending upwardly beyond its extreme upper edge into the recess and projectingv laterally into the path of the lower sash member for engagement thereby, whereby as the lower sash member is opened it moves independently of the. upper sash member until it engages the bracket and thereafter the two move in unison into the recess and the upper edges occupy a staggered relation accommodated tothe recess offset.
